Clemco bulk abrasive blast machines, called Big Clems, are large, durable machines designed for jobs requiring multiple blast operators. They come in three sizes holding 60, 120, or 160 cubic feet of abrasive. Big Clems can be stationary, towable for on-site use, or highway towable for transporting loaded. Each operator station includes pneumatic or electric remote controls. The machines use an automatic metering valve to control abrasive flow and allow switching media types as needed. Big Clems are safe, reliable, and efficient for large-scale blasting jobs.

Blast Machines
N Safety
N Reliable Performance
N High Productivity
Clemco Big Clem multi-outlet,
bulk abrasive blast machines
are rugged, reliable, and
efficient. Designed for large
jobs, where multiple blast
operators are needed, the Big
Clem offers the convenience of
a large supply of abrasive,
loaded at one time, ensuring
more blast on time, and saving
the time and labor of refilling
smaller machines.
Big Clems are available in
three standard sizes: 60, 120,
and 160 cubic feet abrasive
capacity and, depending upon
the model, for up to four blast
operators. Units are rated 125
psi working pressure with 150
psi offered as an option. Each
model is available as stationary,

2. Quantum Metering Valve

N Metering takes place upstream—not at

N Normally-closed design requires com-

N 45-degree abrasive feed assures constant,
uniform abrasive flow.

Durable Transport System
N Big Clems are well-balanced with well-distributed tongue

load capacity.
N Towable models feature rugged trailer assembly for nego-
tiating rough terrain.
Wheels and tires rated for easily handling load at highway
speed.
N Highway models equipped with four-wheel electric
brakes, emergency breakaway switch, and high-visibility
tail lights, brake lights, and turn signals.
